摘要
本文探讨了面向Web服务发现的本体知识库的构建方法及其形式化描述。作为语义Web服务的发现框架中数据层和语义层,面向Web服务的本体知识库与一般的常识知识库不同,它既要表达领域本体的知识(本文涉及旅游领城知识),又涉及到Web服务的形式化描述以及个人兴趣模型的描述,以支持形式化的规范查询请求,并应用本体间的关系最终实现Web服务智能发现。本文通过一个Web服务发现实例说明此模型的应用价值,并与传统的本体知识库进行了对比。
This paper proposes the construction method and the formal description of Web Service Discovery Oriented Ontology-based Knowledge Base（WOKB）. As the data layer and semantic layer of the whole framework of semantic Web services discovery, （WOKB） is different from traditional knowledge base. It will represent not only the domain knowledge （domain in this paper is travel domain）, but the formal description of Web service and even the description of personal interest model to support the formal specification of query request and finally realize the objective of discovering the Web Services through the way of manipulating the relations between ontology. This paper shows the applied merit of this model through illustrating a use case of Web services discovery, and then compares with the traditional knowledge bases.
